I think it is a bit of a stretch to have AJ beating any top guys at this stage. Although Fury lost, he put up a good fight and showed that he is still very good.
Yeah Fury would stop him but I reckon he would take his time a bit and would out jab AJ before timing him with power shots and likely stop him between rounds 6 and 10
Fury comes in the Wilder 2 shape, he destroys AJ. However Fury has aged tremendously in the last 2 years thanks to his indisciplined lifestyle
